We investigate bistatic STAP performance. We show that typical bistatic clutter environments appear nonstationary. Nonstationary behavior exacerbates STAP implementation. In the absence of corrective measures, SINR losses due to covariance estimation error approaches 30 dB for the numerical examples considered herein. Using localized STAP processing coupled with a time-varying weight procedure, we show that much of the performance loss can be restored.
